A few people have come wondering about Bitcoin in Africa and i thought too as well until i was informed that they are quite comfortable in their "Mpesa" system, that really does ALOT for them, all through their phones. It's a shame as its a prime example of use case for crypto, but a corporation did it instead
https://en.wikipedia.org/wiki/M-PesaYou are generalising your thoughts based on just two parts of Africa (Kenya & Tanzania) where M-Pesa is basically used. Have you heard news about other parts of Africa like Nigeria? Bitcoin is already storming most parts of Africa with great potentials. There are already Bitcoin exchange platforms for example in Nigeria to the Fiat currency (remitano, Luno etc) and I know few people who even trade with bitcoin. There is a very huge potential and great promise for Bitcoin.
Only thing I see with Africa is that the infrastructure. I don't know if African country has the setup like Internet that will really help bitcoin their exposure to a large public. How can they take advantage of bitcoin if proper infrastructure like internet is not set-up? So for me, establishing facilities (buildings, power and internet) should be the priority.
You are right in a way regarding infrastructure in most parts of Africa when compared to developed countries but it is not as bad as the outside world portrays it. I am an African, a Nigerian precisely, I use Bitcoin and I have Internet 247 every month on my mobile. So as majority of other part of the country. Like I said, we might not be where we want but it is not as bad as portrayed or assumed by people outside Africa. You don't have a clue how Bitcoin has helped me personally in international exchange compared to when using western union, foreign transaction limits via banks, paypal and the rest.
